main.xml file is not reachable/accessible

I downlaoded an example from the Internet to learn more about the AugmentedReality.

And when I tried to import the project, eclipse couldnt find any project and then, i decided

to copy all the files one by one in a new project I created. But, when I tried to fix some

error, I could not fix and error reads: "main canot be resolved or is not a field"

this error appeared around 'setContentView(R.layout.main);' despite of, in the resources file

there is a main.xml file, but eclipse cant find it.

any suggestions to fix such an error?

Look for

import android.R

Delete it, then clean your project and things should start working again

I think you have an import like:

import android.R;

Remove it and your problem should be gone.
